In just its third all-new big twin in 80 years, Harley has unleashed the exciting new Milwaukee-Eight. As Alex Bozmoski, Harley’s Chief Engineer of New Products puts it, “It’s a brand-new motor, tip to tail.” The “Eight” in the new engine’s title indicates the utilization of 8 valves. Interestingly, the octet of valves is actually reminiscent of the power-train of the Harley board track racers of the company’s early years.

To get the most out of the new 107 CI Milwaukee-Eight engine technology that powers much of the 2017 Harley FL line, K&N has developed the K&N 63-1138 air intake. The 63-1138 is designed to enhance the visceral riding experience in a very exciting way. The intake is designed to improve throttle response with a significant increase in clean airflow to the new engine.

In keeping with that visceral riding enhancement theme, the 63-1138 emits an aggressive and satisfying engine growl. When running the 63-1138 the deep breathing Milwaukee-Eight’s intake sound is unleashed.

The performance enhancement that the 63-1138 offers up for the Milwaukee-Eight engine is a direct result of careful engineering. The intake starts with a special billet aluminum throttle-body mounting plate that attaches to a mandrel bent aluminum intake tube.

K&N knows you want your Harley fully protected from the ravages of the road. K&N’s oil-impregnated filter media has been proven over 4 decades of real world testing. Not only will your Milwaukee-Eight engine breathe freely, it will also breathe clean.

The intake comes pre-oiled and ready for a simple, straightforward installation on your Harley FL model. When it is time to clean the element, that process is easily accomplished with a K&N recharge kit like the 99-5000. For added protection and a unique look, the filter element can be dressed in the RC-3680DK filter wrap.

The intake comes in two distinct finishes to complement your Harley’s styling. The 63-1138 is powder-coated in an aggressive black finish. While the 63-1138C features a gleaming chrome finish.

Everything that is needed for easy installation is included in the 63-1138 kit
